I use a Panasonic CF-19 as my main machine, which has a touch screen and is convertible to become a tablet instead of a notebook. Today I was so lazy and wanted to use it the first time as a kind of ebook reader and wanted to use the touch input for scrolling the book. Bingo - the input wasn't rotated. I used to write four little scripts and added four keyboard mappings to openbox rc.xml script.
I read in the forum, that (a long time ago) someone was on the search for the same solution, so for anyone searching next, here are the scripts ...
rotate-inverted
#/bin/bash
xrandr -o inverted
xinput set-prop 'Fujitsu Component USB Touch Panel' 'Coordinate Transformation Matrix' -1 0 1 0 -1 1 0 0 1
rotate-normal
#/bin/bash
xrandr -o normal
xinput set-prop 'Fujitsu Component USB Touch Panel' 'Coordinate Transformation Matrix' 1 0 0 0 1 0 0 0 1
rotate-left
#/bin/bash
xrandr -o left
xinput set-prop 'Fujitsu Component USB Touch Panel' 'Coordinate Transformation Matrix' 0 -1 1 1 0 0 0 0 1
rotate-right
#/bin/bash
xrandr -o right
xinput set-prop 'Fujitsu Component USB Touch Panel' 'Coordinate Transformation Matrix' 0 1 0 -1 0 1 0 0 1
I got the name of the touch input screen via xinput list.
I added the four scripts as key combinations in the rc.xml of openbox:
<keybind key="W-A-C-Left">
<action name="Execute">
<startupnotify>
<enabled>true</enabled>
<name>Xrand</name>
</startupnotify>
<command>rotate-left</command>
</action>
</keybind>
<keybind key="W-A-C-Right">
<action name="Execute">
<startupnotify>
<enabled>true</enabled>
<name>Xrand</name>
</startupnotify>
<command>rotate-right</command>
</action>
</keybind>
<keybind key="W-A-C-Up">
<action name="Execute">
<startupnotify>
<enabled>true</enabled>
<name>Xrand</name>
</startupnotify>
<command>rotate-normal</command>
</action>
</keybind>
<keybind key="W-A-C-Down">
<action name="Execute">
<startupnotify>
<enabled>true</enabled>
<name>Xrand</name>
</startupnotify>
<command>rotate-inverted</command>
</action>
</keybind>
As a last addition, I added a line to my openbox autostart, to calibrate the touch screen on every start:
xinput set-int-prop "Fujitsu Component USB Touch Panel" "Evdev Axis Calibration" 32 293 3989 69 3591 &
To know the correct calibration, you need to use the tool xinput_calibrate.
I hope, this might help someone else
